Multifocal Contact Lenses
Whether you enjoyed perfect vision or had an uncomplicated corrective lens prescription for nearsightedness/farsightedness in your younger days, the advent of middle age can bring some unwelcome changes in the way your eyes refract incoming light. If you seem to be having more and more trouble reading or focusing on fine visual details, then you're suffering from a common age-related issue called presbyopia. But that doesn't mean you have to give up wearing contact lenses in favor of bifocal, trifocal or multifocal "progressive" eyeglasses. Here at Hobson Eye Associates, we can create perfectly-fitted multifocal contact lenses that correct multiple fields of vision simultaneously.
Are Multifocal Contact Lenses Right for You?
Presbyopia tends to start after the age of 40, when the intraocular lens loses some of its ability to flex -- a necessary skill for switching focus from near images to distant ones and vice versa. As the lens grows stiffer, you find it harder and harder to adjust your visual focus, and the extra effort may cause chronic eye fatigue, muscle strain and headaches. Corrective lenses for presbyopia contain multiple prescriptions, so to speak, distributed across separate or blended zones. While this technology used to be confined to eyeglass lenses, today's contact lenses can also be made with multifocal zones to correct both near vision and distance vision.
There are a few different types of multifocal contacts, and you may have to experiment to find the type that works best for you. These categories include:
- Concentric - Concentric lenses are a common and popular type of multifocal lens. They place the near vision in the center of the lens, surrounded by alternating rings of other correction powers. The eye learns how to work with the different rings to focus on whichever one is needed at the moment.
- Translating - These contacts position the distance field toward the top of the lens and the near field toward the bottom.This arrangement is maintained by making the bottom of the lens slightly heavier so it stays put. You select the visual field you want by gazing upward or downward.
- Aspheric - These multifocals are also called "simultaneous" lenses because the different correction powers are all placed toward the center of the lens. The eye must learn to pick out the correction it needs.
Get Your Multifocal Contacts at Hobson Eye Associates
Getting fitted for multifocal contact lenses is no different than the teasing and measurement process used for single-vision contacts. We take detailed measurements of your cornea and pupil to make sure that both the lenses and its various vision fields line up with your eyes just right. It takes time to get the hang of these lenses, but if you just don't feel like they're right for you, we can still correct your presbyopia with other options such as monovision contacts (near correction in one eye, distance correction in the other).
